Red Hat Product Errata RHSA-2004:106 0 normal SHIPPED_LIVE Important: kernel security update 2004-04-21 04:00:00 UTC

Description Mark J. Cox 2004-02-16 13:49:19 UTC 
Paul Starzetz discovered a flaw in return value checking in mremap()
in the Linux kernel versions 2.4.24 and previous that may allow a
local attacker to gain root privileges. No exploit is currently
available; however this issue may be exploitable. 

Affected: 2.1AS-ia64 2.1AW-ia64

Embargoed until Feb18
